There are 364 first-grade students in park elementary school. if there are 26 more girls than boys, how many girls are there?

Last one and the bottom answer choice is y=(x-4)^2+1 you guys!

Using elimination, what is -4x+2y=-12 4x+8y=-24

Which sum or difference identity would you use to verify that cos (180° - q) = -cos q? a.) sin (a -b) = sin a cos b – cos a sin b b.) cos (a -b) = cos a cos b – sin a sin b c.) cos (a -b) = cos a cosb + sin a sin b d.) sin (a + b) = sin a cos b + cos a sin b
